Detailed Description

internal class representing a single font glyph.

For TrueType fonts initially all FontGlyph's are empty (getImage() will return NULL), but they are filled by demand.

Member Function Documentation

float CEGUI::FontGlyph::getAdvance ( float  x_scale = 1.0 ) const

inline

Return the horizontal advance value for the glyph.

The returned value is the number of pixels the pen should move horizontally to position itself ready to render the next glyph. This is not always the same as the glyph image width or rendererd advance, since it allows for horizontal overhangs.

float CEGUI::FontGlyph::getRenderedAdvance ( float  x_scale ) const

inline

Return the rendered advance value for this glyph.

The rendered advance value is the total number of pixels from the current pen position that will be occupied by this glyph when rendered.
